To provide a shock absorbing device 1 improving absorbing performance of collision energy.SOLUTION: The shock absorbing device 1 includes: a vertical pair of an upper wall section U and a lower wall section L which are extended in a vehicle longitudinal direction in a side section of a vehicle V, are separated from each other in a vehicle height direction, and are oppositely arranged; and a plurality of ribs Rn which are extended respectively in the vehicle longitudinal direction between the upper wall section U and the lower wall section L, are provided side by side at prescribed intervals in a vehicle width direction, and divide a space between the upper wall section U and the lower wall section L into a plurality of partitions Dn extending respectively in the vehicle longitudinal direction. In three partitions D5, D6, and D7 continuous in the arrangement direction of the partitions of the plurality of partitions Dn, an interval between the ribs R6 and R7 constituting the partition D6 in the center in the arrangement direction of the partitions is smaller than an interval between the ribs R5 and R6 and an interval between the ribs R7 and R8, which constitute the partitions D5 and D7, respectively, which are on both sides of the partition D6 in the center.SELECTED DRAWING: Figure 3
【課題】衝撃吸収装置1は、衝突エネルギーの吸収性能を向上させた衝撃吸収装置を提供する。【解決手段】 衝撃吸収装置1は、車両Vの側部にて、車両前後方向にそれぞれ延設され、車両高さ方向に離間していて、対向配置された上下一対の上壁部U及び下壁部Lと、上壁部U及び下壁部Lの間にて車両前後方向にそれぞれ延設され、且つ車幅方向に所定の間隔をおいて並設された複数のリブRnであって、上壁部Uと下壁部Lとの間の空間を、車両前後方向にそれぞれ延びる複数の区画Dnに分割する複数のリブRnと、を備える。前記複数の区画Dnのうち、それらの並び方向に連続する3つの区画D5,D6,D7であって、それらの並び方向における中央の区画D6を構成するリブR6,R7の間隔が、前記中央の区画D6の両隣の区画D5,D7をそれぞれ構成するリブR5,R6の間隔及びリブR7,R8の間隔より小さい。【選択図】図3
